9-Deoxy-PGD1 compounds

ABSTRACT

Prostaglandin analogs with the following cyclopentane ring structure: ##STR1## are disclosed along with intermediates useful in their preparation and processes for their preparation. These analogs are useful for some of the same pharmacological purposes as the prostaglandins, particularly and especially as blood platelet aggregation inhibitors.

The present application is a divisional application of Ser. No. 614,244, filed Sept. 17, 1975, now pending. U.S. Ser. No. 809,248, filed June 23, 1977, and also a divisional application of Ser. No. 614,244, has now issued as U.S. Pat. No. 4,099,014.

The present invention relates to prostaglandin analogs, for which the essential material constituting disclosure therefor is incorporated by reference here from U.S. Pat. No. 4,099,014.
